No, Snap Caps are specifically designed to be used only with vials that have a snap-ring finish—commonly referred to as Snap Ring Vials. These vials feature a specially designed top that allows the "snap cap" to securely attach.
While crimp caps can technically be used on snap-ring vials, they are engineered to perform best with serum finish vials, also known as crimp-top vials. These vials provide the optimal sealing surface and neck structure for crimp caps, ensuring the best performance and seal integrity.
Summary:
- ✅ Snap Caps → Only for Snap Top Vials (with snap-ring finish)
- ✅ Crimp Caps → Best used with Crimp Top Vials (serum finish)
- ⚠️ Do not use Snap Caps on Crimp Top Vials
